Turkeys take 28 I think. Emu's take 55. Crazy. I stress enough with 21.I would love to--one day when I have the appropriate set-up--hatch larger birds: turkeys, swans, emus! I'm curious about how many days the gestation is for turkeys (and any of the larger birds)? I think ducks and geese are only a few days longer. Please, anyone, correct me if I'm wrong. :
